Title: Production of inflation film
Inventor: ISHIDATE HIDEKAZU
IPC: B29C48/92
Filed: 1988-06-17
Abstract: PURPOSE:To produce an inflation film having good quality from a film or sheet by allowing the shape of the tubular film directly above a die head during manufacturing to always coincide with a standard shape. CONSTITUTION:The shape of the tubular film directly above a die head optimum to prepare a good quality film is set to a standard shape which is, in turn, stored. This shape is one ranging from the die head 2 to a part slightly above a frost line 7 and preparatory operation for manufacturing is performed to determine a shape capable of preparing a film having good quality. This shape is taken by a camera 8 to impart data to an image processor 9. The manufacturing of the film is started and the shape of the tubular film directly above the die head is monitored by the camera 8 and the monitored shape is always accurately caught to impart the shape data to the image processor 9. The monitored shape is compared with the standard shape and, when both shapes are different from each other, the blow-out amount of air from a cooling ring 3 is controlled to allow the monitored shape to almost coincide with the standard shape. These processes are mainly performed by a control apparatus 11, an inverter 12 and a blower 5.

Title: Manufacture of semiconductor device
Inventor: MIYASHITA MORIYA
IPC: H01L21/314
Filed: 1986-06-27
Abstract: PURPOSE:To prevent deterioration of an MOS field effect type semiconductor device, by accumulating alkali metal ions and the like in the surface layer of an insulating film by corona charging, and removing the surface layer. CONSTITUTION: In corona charging, a semiconductor substrate 3 is mounted on a grounding plate 2 so that an SiO2 film 32 is directed toward a grid 1, and a DC voltage of -8,000 V is applied to the grid 1. Therefore, corona is charged on the surface of the SiO2 film 32, and the surface potential of -5 V is generated. At the same time, the grounding plate 2 is heated to 250 deg.C, and the temperature is kept for about 30 minutes. Then, Na<+> ions in the SiO2 film, whose temperature is increased to said temperature, are moved readily and are attracted to the surface, which is negatively charged. Then, with the voltage being applied to the grid 1, the grounding plate 2 is cooled, and the temperature of a wafer is decreased to normal temperature. Then, the Na<+> ions are accumulated in the surface of the SiO2 film 32, and a semiconductor substrate, in which said state is fixed, is obtained. Said wafer is immersed in treating liquid, in which, e.g., 30% hydroflouric acid is dilluted by 100 times. Thus the surface layer of the SiO2 film, in which the Na<+> ions are accumulated, is removed by the thickness of about 20Angstrom .

Title: Semiconductor switching circuit
Inventor: MIHARA TERUYOSHI
IPC: H01L27/02
Filed: 1982-08-31
Abstract: PURPOSE:To reduce switch drive current and power loss and enable to integrate circuits by a method wherein a detection resistor for detecting the short circuits of loads is unnecessitated, and then protection circuits are composed of MOS transistor sources which are grounded. CONSTITUTION:When a switching control signal VIN becomes H, the gate voltage VG of a power MOS transistor TR 12 increases at the time constant CG decided by the gate capacitances of an input resistor and the TR 12. When the voltage VG exceeds the threshold voltage of the TR 12, the TR 12 conducts, and accordingly the drain voltage VDS begins to decrease. On the other hand, the output V1 of a differential type delay circuit composed of an MOS TR 18 and a condenser 19 sharply rises and slowly falls. Thereby, an MOS TR 17 turns from the state of conduction to that of non-conduction; an MOS TR 13 does not conduct, and then the TR 12 continues to conduct. While the TR 17 becomes non-conducted, TR 13 conducted, and TR 12 non-conducted after a fixed time at the time of the short circuit of the load 11. This constitution of circuits enables the integration because of no power loss all the time and composition by means of MOS TR sources which are grounded.

Title: Device and method for planarization
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/304
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method by which the surface of a work can be planarized at a low cost, while the quality deterioration of the work caused by scratches is suppressed. SOLUTION: The projecting sections of a work 31 are cut off by rolling a circular blade 34 on the work 31 while an object 31 is rotated. Therefore, the quality deterioration of the object 31 caused by scratches can be suppressed, because the blade 34 is not slid in the diametral direction of the rotation. In addition, since the projecting sections of the object 31 are removed with a high throughput while the breakage of the blade 34 is suppressed, the surface of the object 31 can be planarized at a low cost.

Abstract: PURPOSE:To prevent an inter-code interference by multipath and to enable the high-quality and high-speed radio communication by sending a signal while changing the carrier wave frequency of a transmission signal so as to separate the direct wave and the delay wave and changing the band of passing the accepted signal at the time of reception. CONSTITUTION:A transmitter 1 gets a response on the propagation characteristic of a radio carrier path from a receiver 2. The transmitter 1 calculates the charp frequency interval and cycle based on the propagation characteristics of the accepted radio carrier path. The result of the charp frequency interval and the cycle is recorded on a memory. The transmitter 1 changes the carrier wave frequency of a transmission signal so as to separate the direct wave from the delay wave at the time of packet transmission based on the recorded result and send out the signal. On the other hand, the receiver 2 the pass band of the received signal is changed according to the change of the carrier wave frequency. The received signal is divided into the direct wave and the delay wave. Thus, the inter-code interference by the delay wave is reduced and the high-quality radio transmission is enabled.
